Therefore, the cooling speed of the preforms is one of the key factors in the production efficiency of the bottle blowing machine. The traditional bottle blowing machine preform cooling device usually adopts a static cooling method, that is, the preforms are cooled at a fixed position, which has a slow cooling speed and low efficiency, and is easy to cause the preforms to deform, affecting the product quality. Therefore, a rotary bottle blowing machine preform cooling device is needed;

[0003] Among them, the "rotary bottle blowing machine preform cooling device" disclosed in the application number "CN201120026119.8" is also an increasingly mature technology, including a preform turntable, an outer track is installed on the outer side of the preform turntable, the heated preform is placed between the outer track and the preform turntable, and the mouth of the preform has a preform insertion head, which is characterized in that an inner cooling water plate and an outer cooling water plate are respectively installed under the preform turntable and the outer track, and the inner cooling water plate and the outer cooling water plate are respectively provided with inner cooling water holes and outer cooling water holes, cooling water flows through the inner and outer cooling water holes, and the inner and outer cooling water plates cool the middle part A of the preform body. In this solution, the inner and outer cooling water plates are installed under the preform turntable to cool the middle part of the preform body, so that the stretching of this part of the preform is reduced to ensure the quality of the plastic bottle;

[0004] However, the above method still has the following defects in actual use: the preform body is easily scratched and worn by the cooling device during movement, and the device only cools the two sides of the preform body, and the cooling range is narrow, which easily increases the product quality problems caused by local overheating of the preform body during the bottle blowing process.
